PRIORITY CLAIM

This patent application claims the benefit of pending prior U.S. Provisional Patent Application Ser. No. 60/850,940, filed Oct. 11, 2006, by Sydney W. Baumgartner for SNEEZE GUARD, which patent application is hereby incorporated herein.

BACKGROUND

Sneeze guards are typically used in conjunction with food buffets and the like found in banquet halls, convention centers, country clubs, night clubs, restaurants and other institutions.

Compliance with food service health and safety codes requires a barrier or shield between a customer and the food served by a restaurant or other food service institution. In order to comply with such codes, a variety of sneeze guards currently exist. However, these sneeze guards generally have several problems.

First, efficient utilization of floor space often requires set up and tear down of food buffets and similar other food serving areas on a frequent basis. Conventional barriers pose several problems in this regard. Foremost, it is difficult for a single person to efficiently set up or tear down a conventional serving line comprising several sneeze guards. Most prior sneeze guards have been rigid, cumbersome devices, sometimes with lights and/or a counter attached. See, for example, U.S. Pat. Nos. 5,082,334, 4,013,880 and 3,847,250. Also, as a result of being cumbersome, prior art sneeze guards have been prone to being scratched and broken as they are carried from a storage area to a serving line.

The typical guards for a large establishment can also require extensive and valuable storage space, as they are not foldable or stackable. Furthermore, many guards are, constructed such that the barrier shield may not readily be removed for cleaning or replacement thereof. Sneeze guards are typically deficient in terms of portability, durability, efficiency, and attractiveness.

Another disadvantage of prior sneeze guards is the requirement for frontal support elements that can interfere with access to food by patrons or by personnel who continually restock the food items of a buffet. See, for example, U.S. Pat. Nos. 4,892,366 and 3,817,310.

DETAILED DESCRIPTION

FIGS. 1-5 illustrate an exemplary sneeze guard. FIGS. 8-39 illustrate various configurations and components of the sneeze guard shown in FIGS. 1-5. The sneeze guard shown includes a guard assembly A and a pair of legs J. In an embodiment, legs J may include a first portion C and second portion D for supporting guard A.

Leg portion C (which may also be referred to as upper portion C or inner tube C) may be foldable and detachable with respect to the guard assembly via locking spring-pin assemblies shown adjacent reference character B at each of the legs. Leg portion D (which may also be referred to as lower portion D) may include, but is not limited to, an outer tube D. The inner tube configuration of leg portion C and outer tube portion of leg portion D may be exchanged with one another.

The female parts of spring-pin assembly B may include a sleeve (also referred to as a connecting tube) shown adjacent reference character B welded to the side of the upper frame section for acceptance of leg portion C. Holes may be drilled into the rear and inner walls of each sleeve for acceptance of a spring-pin (the holes may be offset by 90 degrees). The upper ends of leg portion C may contain a spring-pin. A lower bushing and an upper bushing cap take up slack between the leg portion C and sleeve B and provides a smooth, reduced friction surface for insertion and rotation of the legs. The bushing cap also serves to cover the upper open end of sleeve B, the open end of tubular leg portion C, and weld lines between sleeves B and upper frame section.

In an embodiment, leg portion D (or second portion D) may be foldable and detachable with respect to leg portion C via locking spring-pin assemblies F and G. Locking spring-pin assembly F is disposed on the end of leg portion D for attachment to leg portion C. Locking spring-pin assembly G is disposed on the end of leg portion C for attachment to leg portion D. In an embodiment, locking spring-pin assemblies F and G may include similar configurations as spring-pin assembly B described above.

It should be appreciated that the height of first portion C and second portion D may be adjusted by repositioning locking spring-pin assemblies with respect to one another as shown between Position #1 in FIG. 3 and Position #2 in FIG. 4. Such adjustments changes the distance of a region E (which may be referred to a connection region E or an adjustment mechanism E).

In an embodiment, adjustment within region E may be configured to serve as an elevator to raise and extend the entire guard assembly. For example, this extensions may be a distance of four inches.

Guard A may include a pane housed in a channeled tubular frame. The channeled tubular frame may be constructed of aluminum tubing. The channeled tubular frame may have a diameter of approximately one inch (2.54 cm) and a length-wise channel approximately one-half inch (1.26 cm) deep and 5/16″ (0.8 cm) wide. For example, dimensions for the guard frame of 16½″ (42 cm) high and from four to six feet (122 to 183 cm) wide may be suitable for most uses.

In an embodiment, pane H may include an acrylic panel. Such an acrylic panel generally has the advantages of being light weight and shatterproof. In another embodiment, pane H may include glass or other transparent material.

The guard A, inner tube C, outer tube D, and other portions of the sneeze guard may be painted, treated or “powder coated” in a variety of colors.

In other embodiments, FIGS. 6 and 7 illustrate sampler style stands with fixed legs that rotate. FIG. 6 may be a 14-inch stand, which is also shown in FIGS. 46-49. FIG. 7 may be a 18-inch stand, which is also shown in FIGS. 40-45.

In an embodiment, the pair of legs may have having a first portion and a second portion rotatably coupled to one another. The pair of legs may also include spring-pin assemblies for mounting the guard assembly on the legs. Each of the legs may also include spring-pin assemblies for mounting the first portion and the second portion to one another so as to allow independent pivoting each of the legs with respect to the guard assembly. In various embodiments, the legs may be rotated to either an open position (e.g., configuration for use) or closed position (e.g., configuration for storage).

The various embodiments of the sneeze guards are labor saving. For example, one person may quickly assemble a multitude of sneeze guards so as to erect a buffet or serving line. The sneeze guards may be constructed as light weight, yet durable. The sneeze guards may be quickly folded for ease of portability or storage.

In addition, sneeze guards may be used individually, side by side, or back to back in an attractive manner. In one embodiment, support legs sweep back and away from the access side of the sneeze guards, thereby eliminating bothersome frontal support members. For cleaning or replacement, sneeze guards may include a removable guard assembly or barrier shield.
